These clocks are only modified as part of DRAM frequency switches during which DRAM itself is briefly inaccessible. The switch is performed with a SMC call to by TF-A which runs from a SRAM area; upon returning to linux several clocks bits are modified and we need to update them. For rate bits an easy solution is to just mark with CLK_GET_RATE_NOCACHE so that new rates are always read back from registers.

Applied, thanks. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
